Check in was at 3pm, check out was at 10am. Staff does not allow even 30 minutes late check out, asking that we buy 1hr late check out at 2000yen.
Breakfast was at 7am to 9am. Basic breakfast. If you are there at 830am, you need to take out the breakfast, take out box is provided by the hotel.
We were there earlier, before the snow park opened. Staff was not too helpful with recommendations of other snow amenities that we can do. In the end, we found Echigo Yuzawa Ropeway on our own, which is a short walk (5 mins from hotel). Absolute fun - you sit a cable car up, and then the view.on top is breathing taking and there's a good Italian restaurant up there.
The bathhouse and onsens are great. Decent size and comfortable and clean. There was a child-size snow sledge for kids, which is quite fun (even though the ski park was not opened when we were there).
